In February, Google and NASA scientists took the smartphone prototypes on a zero-gravity test flight. The engineers used the flight to calibrate the device's motion-tracking and positioning code to function properly in space.
NASA scientists say they envision 3D-enabled Spheres could be used to inspect the outside of the space station or the exterior of deep space vehicles.
While Google's 3D technology is set to go to the space station this summer, a SpaceX resupply mission, which will carry legs for the humanoid robot working on the orbiter, is slated to launch this afternoon.
SpaceX was set to launch its third resupply mission on Monday but the liftoff was postponed due to a leak in the Falcon 9 rocket that will carry the Dragon cargo spacecraft aloft.
Since the summer of 2013, Google and NASA have been working together to bring 3D mapping technology to the International Space Station.
